Escaping user input (including {code}) inside {code} block

[Sean Williams]

Hi folks,

I'm making a Jira API client that posts issues from our monitoring services. I'm trying to (correctly) present forwarded data inside a {code} block, without said data breaking rendering in Jira.

My first thought was to simply replace { and } with backslash-escaped variants of themselves, but this causes the backslashes to present to the user.

I tried making a code-block whose contents were the literal string {code} in the Visual editor inside Jira, and saving the page caused two empty code-blocks to appear. My assumption is that Jira is not actually doing any escaping here, so it sees three {code} blocks and processes it as the start/end of a first block, then the start of a second one.

Is there a "correct" way to do this? Did I have the misfortune of uncovering a rendering bug in Jira's markup?
